Square Drive Sheet Metal Screws

If you're working with sheet metal, you need sheet metal screws. These screws are specifically designed to drive through the unique and tough construction of the material, which conventional screws can't accomplish.

FMW Fasteners carries Simpson square pancake-head, self-tapping sheet metal screws made from stainless steel for maximum strength and durability. 

What Is a Sheet Metal Screw?

A sheet metal screw is commonly used to fasten sheet metal to a variety of materials including other metals, wood, aluminum and plastic. Sheet metal screws are fully threaded for the complete length of the shaft to increase retention between materials. They also have sharp tips and threads to more effectively pierce sturdy surfaces, and they are typically made from stainless steel for enhanced rust and corrosion resistance. 

There are two main types of sheet metal screws:

  • - Self-tapping: Forms its own threads in a pre-drilled hole.
  • - Self-drilling: A type of self-tapping screw that has the added feature of a drill point, which eliminates the need for a pre-drilled hole. 

Self-tapping and self-drilling sheet metal screws make for a faster installation process that is preferred by professionals and DIYers who use sheet metal for construction, roofing, HVAC and gutter repair applications.

Sheet metals screws also come in different head and slot types. The Simpson sheet metal screws we carry have a low-profile, "pancake" head that is about two-thirds of the height of a standard round-headed screw. Square drive screws for sheet metal feature a square-shaped recess or slot at the top of the head, which offers increased slip resistance while drilling.

How to Use Sheet Metal Screws

To use square drive sheet metal screws, gather your materials and follow these basic steps as a guide:

  1. - Clamp the two objects that you want to fasten together. 
  2. - Press the screw firmly onto the surface, making sure it stays in the desired spot.
  3. - Start to drill at a slow speed.
  4. - Once the screw begins to pierce the material, you can increase the drilling speed.
  5. - When the screw becomes tight, stop drilling. Any further drilling beyond this point will strip the slots. The threads of the screw may also become stretched out if you drill in too tightly, which can decrease the screw's strength.

Be sure to follow any specific instructions associated with the materials or application you are using, and consult a professional when in doubt.
